Outside neck dia. of loaded 25-06?

Hey fellas, Am trying to order a bushing for a Redding S bushing fl die. The man at sinclair support said to measure the outside of a already loaded round and order that bushing size. He also stated that for my 25-06 it should be between .280-.283. When I got home I measured and am comming up with .284 on most rounds with an occasional .285 popping up. I am using WW super brass and 115gr bergers though the bullet should make no diffrence. Do any of yal have some rounds with this brass you could measure and tell if I'm on? Thank's, Brad

Your measurement is within reason. But, I disagree with the Sinclair tech.

If you just measure the loaded OD and get that bushing, I think you've got a problem because you would be sizing the ID to .257" not accounting for spring back. Hence, you'd likely end up with more than a few at .258" ID which is really bad.

Based on your .284" measurement, I'd order .280-.282" bushings expecting to use .281" with your current lot of brass.

Your suppose to subtract .001 from that reading. Or just buy a bunch keep the one you need send the rest back.
